An 8-y-old female rhesus macaque (Macaca mulatta) presented for swelling of the left lower limb distal to the inguinal region and associated with the femoral artery. Physical and ultrasound examinations suggested an arteriovenous fistula combined with a pseudoaneurysm. After review of possible treatment options, we determined that open surgical repair was the best course of action. The pseudoaneurysm and arteriovenous fistula were surgically resected, and the macaque recovered without complication.

A 33-year-old woman presented with a rare intracranial pial arteriovenous fistula manifesting as monoparesis and hypesthesia of the right lower extremity. Computed tomography demonstrated an approximately 10-mm diameter subcortical hematoma in the left postcentral gyrus. Two months after suffering the ictus, angiography demonstrated a pial arteriovenous fistula in the late arterial phase fed by the left paracentral artery and drained into the left precentral vein. No nidus or dural arteriovenous fistula was detected. Left parietal craniotomy was performed and the pial arteriovenous fistula was extirpated by electrocoagulation. Intraoperative angiography demonstrated disappearance of the fistula. She experienced no postoperative neurological deterioration, but hypesthesia of the right leg persisted. Obliteration of the pial arteriovenous fistula was reconfirmed by postoperative angiography. She suffered no rebleeding episodes during the 36-month follow-up period. Pial arteriovenous fistula causing mild symptoms should be treated by flow disconnection because the direct arteriovenous shunt and attendant high blood flow usually results in huge venous varices. To determine whether direct surgery or endovascular treatment is appropriate, the position and shape of the lesion must be known.

Post-traumatic arteriovenous fistulae (AVF) can lead to congestive heart failure and limb ischaemia. The objective of this study was to determine the presentations, interventions, and outcomes (morbidity and mortality) of the patients treated with traumatic AVF at a university hospital between January 1995 to December 2018. Nine patients (M: F 8:1) with median age of 30 [IQR 24.5] years were included in the study. They presented as 'missed injuries' with median delay of 4 [IQR 55.25] months. Most had penetrating injuries and presented with painful limb swelling, pain, and venous ulcer. Superficial femoral and popliteal were the most involved vessels. Seven (77.7%) patients had surgery, while 2 (22.2%) had endovascular interventions. Open arterial reconstruction was performed with interposition vein in 4 (44.4%) or with prosthetic grafts in 1(11.1%) patient. There was no peri-operative morbidity or 30-day mortality. All patients had smooth recovery with limb salvage rate of 100%.

INTRODUCTION
Spinal perimedullary arteriovenous fistula (PMAVFS) is a rare intradural vascular malformation with a high rate of misdiagnosis. In adults, most spinal PMAVFs are small and low-flow, starting with progressive spinal dysfunction.
PATIENT CONCERNS
The patient was a 58-year-old male who presented with both lower limbs numb with intermittent walking weakness, obvious at both ankles, and no obvious inducing and relieving factors. The local hospital considered the diagnosis of lumbar disc herniation after MR examination; he was treated with lumbar fixation and fusion.
DIAGNOSIS
After admission, a ce-MRA examination showed that the left spinal artery at the T10 level showed small branch blood vessels in the local area. The distal end was unclear, which seemed to be connected with the drainage vein of the spinal cord. The digital subtraction angiography (DSA) result indicated that the left intercostal artery of T10 sent the Adamkiewicz artery down to the level of L4, and an arteriovenous fistula was seen. The fistula was located at the lower edge of the L4 level and then drained to the upper premedullary vein to the level of T4 after a short descending. It was finally diagnosed as a perimedullary arteriovenous fistula.
INTERVENTIONS
It was cured by cutting the arteriovenous fistula in the spinal canal by indocyanine green-assisted angiography.
OUTCOMES
we report a case of PMAVFS misdiagnosed as lumbar disc herniation with resection and internal fixation. In our hospital, the final diagnosis was a perimedullary arteriovenous fistula, which was cured by cutting off the arteriovenous fistula within the spinal canthus.
CONCLUSION
Spinal perimedullary arteriovenous fistula (PMAVFS) is a rare intradural vascular malformation with a high rate of misdiagnosis. In adults, most spinal PMAVFs are small and low-flow, starting with progressive spinal dysfunction. It is hoped that this can provide warnings to more neurosurgeons and reduce the occurrence of misdiagnosis.

BACKGROUND This report presents a rare case of a traumatic innominate artery to left innominate vein fistula following a stab wound to the base of the neck. CASE REPORT We report a case of a 23-year-old patient with a traumatic innominate-innominate arteriovenous fistula, after being stabbed in the suprasternal notch area 3 years prior. The patient presented with fatigue, and shortness of breath on exertion. Examination revealed a wide pulse pressure, bounding pulses, and a continuous murmur on the upper sternal area. Chest X-rays, echocardiography, CT angiography, and cardiac catheterization were useful to aid in diagnosis and work-up for fistula repair. A complex 8-mm fistula between the left innominate vein and the proximal innominate artery was noted, with multiple tortuous channels and demonstrating a reversible left-to-right shunt. After medical optimization, successful surgical ligation and division of the fistula was done through median sternotomy without cardiopulmonary bypass. The postoperative recovery was uneventful. CONCLUSIONS Traumatic innominate-innominate arteriovenous fistulas are rare and can pose a diagnostic challenge. High index of suspicion, careful history, examination, and radiologic evaluation usually result in correct diagnosis. Endovascular and surgical approaches are the mainstay treatment.
